Mitel MiVoice Business/MCD/3300 / DHCP / VLAN problems since switch upgrades
« on: November 30, 2022, 09:17:42 AM »
Hi all,
We have recently upgraded all of our switches to Aruba 6100/6200's. All ports are configured as trunk native vlan 1, trunk access allowed all. Vlan1 is data/default. Vlan2 is voice.
Since the upgrade we are having problems with PC's that are attached to Mitel 6930 phones (LAN ports). Essentially the phones work perfectly and get an IP address on the phone network, which is 3.x but the PC's randomly get IP's from Phone and Data which is 1.x.
Essentially two DHCP servers fighting. Data network has DHCP server on Windows, Mitel phones get it from Phone System.
My question is what's different on these switches that we are missing, the previous HP switches were configured in exactly the same way.
Things I read point me in the direction of Inter-VLAN routing and DHCP traffic passing. But not found concrete documentation on how to prevent this.
Any help appreciated.
